GUICtrlSetData does not update data

Hello

I have been trying to get the GUICtrlSetData command to update the text in a Input control and just cannot seem to get it to work. In my troubleshooting, I can get the text to update if I insert theGUICtrlSetData earlier in the code and manually set the value to something, but if I try to do it after returning from a Sub, it will not. I suspect I have to be missing something very easy.

I've attached a sample of the code. It looks for a *.db file to load. To use it you would need to create a blank *.db file on your hard drive to find.

If anyone can explain why the Input line will not update to the file name after I return from the subroutine, I would be greatly appreciative.

Thanks

Hi jtsteffen,

your handle for the input control may not be accessible if you call it from another function.

Try declaring it as a global variable first. :unsure:

global $i

Func _main()
   $h = GUICreate()
   $i = GUiCtrlCreateInput()
EndFunc

Func _change()
   GUICtrlSetData($i, "New Value")
EndFunc

Edit: Added example.

jtsteffen,

Your _ClearAllData function destroys not only the data but also the ControlIDs of the Input controls. :unsure:

Just remove these lines:

$hFolder1 = ""
$hFolder2 = ""
$hFile1 = ""
$hFile2 = ""

from the function and all works as it should. :>
